A is the base-frame,having a main drivingwheel, A, mounted upon an axle,A upon one side, and provided with a smaller wheel,

A, upon a downwardly-curving axle, A upon the other side, and adapted tobe drawn forward byhorses attached to atongue, A. Fixed upon top of thisframe A is a cam-frame (see Fig. 3) having an outer rib, a, and an innerrib, (L as shown.

B is an arm projecting from the cam-frame, and provided with two toothedsegments, b I), (see Figs. 14, 15, 16, and 17,) adapted to engage witheach other, the segment I) having an upwardly-projecting spur carryingan antifrietion roller, I), while the segment b'i is provided with acurved finger or hook, I), as shown. B is another arm, projecting fromthe opposite side of the cam-frame from the arm B, and provided withtoothed segments b 12, (see Figs. 9, 11, 12, and 13,) the segment I)having an arm, I), and anti-friction roller b and the segment I)? havinga curved arm or finger b", as shown.

0 is a center post or standard rising from the frame A, and adapted tosupport a circular frame, 0, as shown. Around the outer edge of thisframe 0 is a bevel-gear, G", into which the teeth on a bevel-pinion, 0*,engage. This gear G is mount-ed upon a horizontal shaft, 0 (see Figs. 1and 5,) running in suitable bearings in the frame A, and adapted to -bedriven'by a gear and pinion from the main driving-wheel A", in theordinary manner of driving harvesters, mowers, &c. By this means, whenthe machine is drawn forward, the frame 0 will be revolved around thestandard O.

The frame '0 is formed, as shown in Figs. 1

d radiating from the center of the frame. The frame may be formed withany number of these radial spaces. In Fig. 6 twelve are shown, whichwill be the ordinary number; but in Fig. 1 the frame is shown with fourradial spaces and one partially broken out, so that the parts beneathare less obstructed. In each one of these open spaces (1? a frame, D, isadapted to slide inward and outward.

Pivoted at their centers in each of the frames D, near their inner ends,are small levers 6. (See Figs. 30, 31, and 32.) The lower side of theouter ends of these levers e are provided with downwardly-projectingstuds carrying anti-friction rollers 6 c and upon the outer and 6, byparallel guides (1, into open spaces ends of arms 0", at right anglesfrom each of the levers e, are spurs e projecting upward through openspaces 6 in the frames D.

Upon the outer ends of each of the frames D two curved arms, E E, arepivoted, and each provided with toothed segments g y, engaging with eachother, so that by moving one of the curved arms the other will be madeto move in the opposite direction. F are other segments pivoted to theframes D, and adapted to engage with the segments on the arms E. Thesegments F are each provided with arms F, connected by hollow arms Fwith each of the studs 0 Each of the arms F is formed with slots h wherethey pass over the studs 6 (see Figs. 33 and 34,) and between the sidesof the arms coiled or other springs h are arranged, so that the arms F'will be flexible lengthwise, as hereinafter shown. Each of the curvedarms E is provided with a slot, t, into which the other arm, E, runswhen they are brought around toward each other, as shown in the lowerpart of Fig. l and in Fig. 8.

G is a guide-arm connected by rods G G to thearms E E and with one endat k forked, to pass upon each side of the arm E, while the other end,70", passes into the slot i of the arm E. By this means a guard isformed to protect the teeth on the ends of the arms E E from the flaxwhen the arms are closed upon the gavel.

Each of the frames D is provided wit-h a slot, m, in which is pivotedone end, m, of a series of crank-arms, H, while their other ends, W, areprovided with anti friction rollers adapted to catch into the hookedfinger or arms b on the segment b, as hereinafter shown.

Just back of the gear 0 on the frame (I is a cam-groove, n, in which thefriction'rollers b" b on the segments b and b run. This camgroove n isformed, as shown, with the parts which come between each pair of theguides d a segment of a circle of which the standard 0 is the center,while the portions which come between these segmental portions arecurved inward toward the center, as shown, the ob- I j ect to behereinafter set forth.

K K are two dividers adapted to gather the flax inward and compress itas the machine is drawn forward, to put it in proper shape to be caughtby the pullingarms. The bed-frame A, andthe cam-frame a a and revolvingframe 0 are set at an inclination to the ground, the side next to thewheel A being the lowest, and just in the rear of and partially beneaththe projecting arm B" is an endless slatted belt, L, adapted to berevolved by gears, &c., from the shaft In Fig. 1 one set of the pullingarms is shown at N open and drawn inward, and moving in that positionaround toward the dividers K K, and at N one set is shown just ready tobe thrown outward, while the third set is shown thrown outward, andclosed, in the position they will assume when carrying the flax aroundto the discharge-point. When the machine is drawn forward, the frame 0'is revolved, as before described, and carries the pulling devices aroundwith it.

The anti-friction rollers e e on the levers e are adapted to run in thespace between the ribs a a from'the point +00 to +a and outside the riba from the point +00 to +0. The ribs a a", from the point a to the pointa, are the segment of a circle of which the center of the standard 0 isthe center, and the rib a, from the point a to the point a is also thesegment of a circle of which the standard 0 is the center, but of agreater radius than the section from a a". At a a slight inward orreverse curve is formed in the rib a and this rib connected to the rib aby a web at a, while a similar curved-section, a, is formed as a continuation of the rib a between the points +0. a" and nearly parallelwiththe section a". From the point a to the point a the rib a is in astraight line radiating outward from the standard C, while thecorresponding part, a, of the rib a is in a line parallel with it andwith a shorter rib, a, midway between them, leaving channels a, a, whichalso radiate outward from the standard 0. The end a of the rib a and theend a" of the rib a are curved around, as shown, the object to behereinafter explained.

While the frame G", with the pulling mechanism attached, is revolvingwith the antifriction, rollers'e e on one of the pulling de vices in thespace a a between the ribs a m the arms E E will be held open andinward, as shown in Figs. 1 and 7. Then, when the arms E E have reacheda point so that the rollers e? c are about opposite the channels a a, asshown in Fig. 7 the cam-groove n will have so acted upon the segments bb as to throw the hook or finger b outward to catch the friction-rolleron on the bell-crank lever H and hold the latter stationary, so that asthe frame 0 continues to revolve the bell-crank lever will throw theframe D outward and cause the roller e to run into the channel a, andthe other roller 6 to run into the channel a, as shown in Fig. 8. I

As before stated, the channels a a radiate outward from the standard 0;hence the frame D, when moved outward, will do so in a very short time.As the machine is drawn forward, the dividers K K will gather in a largeamount of the flax and compress it, so that when the frame D is thrownoutward the arms E E will enclasp a bunch of the compressed flax, andthen, when the rollers e e strike the curved ends a a", they'will besuddenly turned around and revolve the lever c, and throw the segment Faround by means of the arm 0 and connecting-rod F and cause the segmentF to act upon the segments 9 g on the arms E" E and close them andtightly compress the flax; and as the frame (3 continues to revolve, thebunch of flax held by the arms will be pulled up by the roots andcarried around to the projection 13", the rollers c e traveling upon therib a from a to a and holding the creased, as desired.

arms E E closed during that part of the movement. In the meantimeanother set of the pullingarms have come into play, caught their gavelof flax and carried it around, and so on continuously. The sets ofpullers will be so close together, and the speed of the frame 0 will beso regulated, that all the flax will be caught by the arms as it iscompressed between the dividers K K The curving of the axle A downward,as shown in Fig. 5, enables the roots of the flax to pass over it, whilethe inclining of the frame A raises the discharge side of the machine,so that the flax will be carried upward as it is carried around and willnot drag upon the ground. The inclination of the frame may be increasedor de- As the arms E E, with their gavels of flax, come around towardthe reverse-curve part a a of the rib c the flax will be thrown overupon top of the endless belt L, and then, when the roller 6" strikes thehooked finger b on the segment b,

(which will be thrown inward at the proper time and held inward by thecam-groove n,) the arms E IE will be thrown open and the gavel of flaxdropped upon the endless belt L and be carried off to one side anddropped upon the ground, out of the way of the machine when it comesaround again. The reverse-- curved portion a a" forms an enlarged spacefor the rollers e e to revolve in when they are turned around by thehook I). The rollers c c then pass on into the channel between thesections (0 a, the latter by their inclination gradually forcing theframe D inward until the point a is reached, from which point to thepoint a it will travel in the segment of a circle, as before described.By these arrangements each pair of the pulling-arms, as they arerevolved, is suddenly thrown outward, grasps a gavel of the flax, pullsit up by the roots, carries it around, and discharges it on the oppositeside of the machine. A crank-arm lever, M, adapted to be vibrated by thecamgroove a, or other means, will be pivoted beneath the frame A at asuitable point to reach beyond the frame 0 and strike the roots ofgavels of flax as they are carried around and knock the earth loosetherefrom.

Having described my invention and set forth its merits, what I claimis 1. In a flax-pulling machine, a frame adapted to be moved forward,and provided with means for gathering the flax into a compact form, arevolving frame carrying a series of oppositely-curved grippingjaws,means for. projecting said jaws outward and closing them to seize agavel of the flax, and means for opening said jaws to discharge saidgavel therefrom and drawing the jaws inward again, substantially asdescribed.
